Imikoreshereze
Ethyl silicate (TEOS) ni amazi atagira ibara, akoreshwa cyane cyane nk'imyenda irinda ubushyuhe, imyenda irinda imiti, ibyuma bihuza silane, organic synthesis intermediates, ndetse n'intangiriro y'imyanda ihumanya ikirere (CVD)SiO2 films mu gice cy'imiti, n'ibindi. Aho ethyl silicate ishonga ni -77℃, naho aho ishyuha ni 165.5℃. Irashonga gato mu mazi kandi irashonga muri ethanol na ether.
Ikoreshwa nk'ibikoresho birinda ubushyuhe mu nganda z'ikoranabuhanga ndetse no mu gutunganya ikirahure cy'urumuri n'icyuma gikingira
Ikoreshwa mu gushushanya neza nk'igikoresho cyo gufata ibumba ry'umucanga; Ubuso bw'icyuma buvugutiwe n'umwuka wa ethyl silicate bushobora gukumira ingese n'amazi. Ethyl silicate ishobora gukoreshwa mu gutera silicon hejuru y'ibyuma, kandi gutunganya ikirahure cy'urumuri bishobora kongera uburyo bwo kohereza urumuri. Ifu nziza cyane ya silica ikorwa nyuma yo gushonga burundu ishobora gukoreshwa mu gukora fosforasi. Ethyl silicate ni ibikoresho fatizo bya silicate. Ethyl silicate ishobora kandi gukoreshwa mu gukora irangi rirwanya ubushyuhe n'imiti. Mu Buyapani, 90% bya ethyl silicate ikoreshwa nk'ibikoresho by'ibanze mu irangi rirwanya ingese (irangi rikungahaye kuri zinc).
Ikoreshwa cyane cyane mu gusiga irangi rirwanya imiti n'irangi rirwanya ubushyuhe, mu gusiga irangi rya silikoni n'ikirahure cy'ubukorikori. Nyuma yo gusiga irangi burundu, ifu nziza cyane ya silikoni dioxyde irakorwa, ikoreshwa mu gukora fosforasi kandi ishobora no gukoreshwa nk'ikintu gihindura imiterere y'imiti.
Tetraethoxysilane ikoreshwa cyane cyane mu birahuri by'urumuri, irangi rirwanya imiti, irangi rirwanya ubushyuhe n'amakorale. Guhindura irangi rirwanya ingese Irangi rihuza, rifata, rikuraho amazi; Gukora amagufwa ya catalyst na silica nziza cyane.
Ethyl orthosilicate ikoreshwa cyane cyane mu birahuri by'urumuri, irangi rirwanya imiti, irangi rirwanya ubushyuhe n'amakole. Guhindura irangi rirwanya ingese. Irangi rihuza, rifata, rikuraho amazi; Gukora amagufwa ya catalyst na silica nziza cyane.
Ibikoresho byo gukingira amashanyarazi mu nganda z'ikoranabuhanga, irangi, ibikoresho byo kuvura ikirahure cy'urumuri, imiti igabanya ubushyuhe, imikorere y'ibinyabuzima, imiti igabanya ubushyuhe mu gutegura organosilicon
Mu kintu cyashyizwemo H+-magadiite, kizakorana na dodecylamine mu bushakashatsi ku kirahuri cy’icyuma kivanze. Gikunze gukoreshwa nk'intangiriro mu gutegura jeli zumutse.
Gupakira no Kohereza
Gupakira: 200kg nk'uko umukiriya abikeneye.
Kohereza: ni imiti isanzwe kandi ishobora gutangwa hakoreshejwe gari ya moshi, inyanja n'ikirere.
Imigabane: ifite ububiko bw'umutekano bwa 500MTs
Bika kandi ubibike
Igihe cyo kubika: Amezi 24 uhereye igihe byakorewe mu ipaki y’umwimerere idafunguye, bibitswe ahantu hakonje kandi humutse, kure y’izuba ryinshi, amazi.
Ububiko bufite umwuka uhagije, Butuma ibintu bishya bishyuha, butandukanyijwe n'ibikomoka kuri okiside, aside.
